Hello ,
The method has worked on Windows 7 and Vista.
Has not been tried on Windows 8 Yet.
Worth a try, let me know the result.
The Murphies Method
I have had this problem as well and tried alot of recommendations but none apparently worked.On the update box on my computer has recent time update tried had NEVER.
So if you have this maybe this will work for you I tried quite a path with all having the same apparent result with the error 8024402F Coming up.
This is such a mad mad world we live in (murphies law seems to be in control.)
Do exactly the opposite what is logical
First set your update setting to NEVER RECEIVE UPDATES, then UNTICK the two boxes below if they are ticked (one about any one can update,) and the other about being informed about available updates.(That one a box comes up are you shore you want not to be notified etc.)
NOW USING MURPHIES LAW Leave all settings as is eg NOTHING SHOULD WORK
NOW CLICK THE UPDATE BUTTON SURPRISE SURPRISE YOU NOW CAN UPDATE.!!!!!
After updating ,check for further updates after the first batch.
Then the settings can be put back to normal eg Receive updates Automatically, the tick the other two boxes.

Hello Thank for your acknowlegement.Looks like you help others so I will paste some information that may explain why this works, there are another 2 solutions given by others that work some times,
As normally you find a solution then try to produce a theory taking in other successes from other methods.
Other methods though more complicated apparent do work some of the time 1/ Resetting time
2/another apparently works some time changing the DNS (although it did not work for me)
3/Also the blame has been put on the service providers.
What ever could be common with this lot.While going through the questions on the site about fault code error 8024402F, one person mentioned something that IS THE KEY TO THE PROBLEM as when the problem started to occur.The KEY PROBLEM ALSO ANSWERS WHY THE OTHER TWO METHODS SOMETIMES WORK, and WHY MURPHIES LAW NEARLY ALL OF THE TIME.
The The THEORY KEY TO THE PROBLEM . In the Months March ,April May, and September October and November. Daylight, Summer Time, Winter Time changes occur at various time through out the world ,which can put my computer time updating no longer matching the time line differential it has with the update server, Because of this NEVER updates any longer as they never agree again.the methods mentioned, eg 1/ resetting the time does correct sometimes,2/ changing the DNS sometimes but say changing DNS to a site in the same country will not work but changing it to a google DNS in a different country may correct.
But the MOST SUCCESSFUL THE MURPHIES LAW what does it do actually cuts OFF ALL TIES (TIME ETC) THE UPDATE SERVER EG NEVER UPDATE,NEVER LET ANYONE ON THE COMPUTER UPDATE,AND COMPLETELY CUT ANY TIE WITH THE UPDATE SERVER. NOW BY PRESSING THE UPDATE BUTTON AS A MANUAL UPDATE NO LONGER IS TIME RELATED BUT SYN. CORRECTLY AGAIN WITH THE UPDATE SERVER (All is well until maybe the next cycle in about 6 months time or hopefully never again.
THIS IS ONLY A THEORY BUT AT PRESENT FULFILS The model of what has been actually has been happening.
Looks Like MURPHIES LAW THOUGH ILLOGICAL as per NORMAL IS ACTUALLY THE MOST LOGICAL SOLUTION OF ALL.
